President Obama took his health care pitch to Minneapolis, Minnesota Saturday where he sought to rally support for his overhaul and pledged to "call out" critics who he accused of spreading misinformation.

Obama also said he will not waste time with those who think "that it's better politics to kill this plan than improve it." He said he could "not accept the status quo as a solution. Not this time. Not now."

Earlier, Obama said in his weekly address he'd work to ensure that health care would be provided to any and all Americans in need of medical attention -- and that more and more families across the country were losing access to affordable services.

"It's an anxiety that's keeping more and more Americans awake at night," Obama said. The president predicted that nearly half of all Americans under 65 years old will lose their health care coverage at some point within the next two years, citing statistics that showed about six million Americans lost their access to care over the past year.

Obama said he wouldn't let that future happen -- and that his health care bill would provide access to all Americans.

"In the United States of America, no one should have to worry that they'll go without health insurance," he said. "Not for one year, not for one month, and not for one day. And once I sign my plan into law, they won't."
